[0008] Patent Document 2: Japanese Unexamined Patent Application Publication No. 2017 - 164537 Summary of the Invention

[0009] (Problems to be Solved by the Invention)

[0010] For kindergarten teachers or nannies, or parents, taking care of infants and young children becomes a relatively large burden.

[0011] For example, even when infants and young children are taking a nap, it is difficult to look away. Therefore, the work burden on kindergarten teachers, etc., or the parenting burden on parents is very large.

[0012] In recent years, as a method of reducing the burden, a human motion sensor is worn on infants and young children so that abnormalities of infants and young children can be detected, such as abnormalities in pulse, body temperature, or a state without body movement. In this case, by detecting an abnormality of an infant or young child with a human motion sensor and outputting an alarm, kindergarten teachers, etc., can be aware of the abnormality, and thus it is not necessary to always stay by the side of the infant or young child.

[0013] However, due to incorrect wearing of the human motion sensor, or the wearing state of the human motion sensor becoming a state unsuitable for detection due to the movement of infants and young children, etc., there may be an output of an alarm.

[0014] In this case, even when the infants and toddlers are in a normal state, the kindergarten teachers have to go to confirm the state. In particular, due to the turning over of the infants and toddlers during their naps, or activities during games, etc., there are many cases where the wearing of the body motion sensor is displaced, resulting in frequent alarms and instead causing the problem of increased workload.

[0015] Therefore, in view of this problem, the present invention proposes a structure of a fastener suitable for wearing a body motion sensor.

[0016] (Measures taken to solve the problem)

[0017] The fastener according to the present invention includes: a main body portion; a regulator portion extending from the main body portion and capable of being elastically bent; and a cover portion connected to the main body portion via the regulator portion. The cover portion is configured to be in a state of being separated from the main body portion by the elastic bending of the regulator portion and a state of being locked to the main body portion in a state of covering the main body portion. In the state where the cover portion is locked to the main body portion, the side surface of the main body portion and the surface of the regulator portion facing the side surface are in a separated state.

[0018] Thus, in the state where the cover portion is locked to the main body portion, due to the bent regulator portion, there is a slight margin in the positioning of the cover portion in the locking direction.

[0019] It is conceivable that in the above fastener, the cover portion is locked to the main body portion in a state of covering less than half of the main body portion.

[0020] Therefore, in the state where the cover portion is locked to the main body portion, a part of the main body portion is in a state of being exposed to the outside.

[0021] It is conceivable that in the above fastener, the main body portion has a protruding portion, and the cover portion has an insertion hole. In the state where the cover portion is locked to the main body portion, the protruding portion is inserted through the insertion hole.

[0022] When removing the cover portion from the main body portion, while pressing the exposed protruding portion, lift it from the main body portion in a manner of peeling off the cover portion, and thus it can easily become a non-locked state.

[0023] It is conceivable that in the above fastener, a body motion sensor having one or more detection portions capable of detecting the physical condition of the wearer is installed on the main body portion.

[0024] Thus, in the state where the fastener is worn on the fabric of the wearer's clothes by locking the cover portion to the main body portion, the body motion sensor is in contact with the wearer's body.

[0025] In the above-described fastener, it is conceivable that the detection unit has at least an optical sensor that determines the contact state with the wearer's body, and the optical sensor is configured to be exposed from a hole formed in the main body portion.

[0026] Thereby, the wearing state of the fastener can be determined by the optical sensor.

[0027] (Effect of the Invention)

[0028] According to the present invention, by the structure of the fastener that can be applied to a human motion sensor, it can be made easy to wear and not easily fall off, and can also adapt to the thickness of clothes, so that it is not likely to occur wearing deviation.

[0047] <1. Summary of the fastener>

[0048] With reference to Figures 1 to 3 , the summary of the fastener 1 in the present embodiment will be described.

[0049] Figure 1 and Figure 2 are the perspective views of the fastener 1, Figure 3 which is a view showing the wearing state of the fastener 1.

[0050] As Figure 1 and Figure 2 shown, the fastener 1 in the present embodiment has: a main body portion 2, with a human motion sensor 5 built therein; a regulator portion 3, extending from the main body portion 2; and a cover portion 4, connected to the main body portion 2 via the regulator portion 3.

[0051] For example Figure 3 As shown, the cover portion 4 is locked to the main body portion 2 by clamping the cloth 50 of the clothes of the infant Hm, and the fastener 1 is worn on the clothes of the infant Hm.

[0052] By wearing the fastener 1 on the clothes of the infant Hm, the physical condition of the infant Hm can be sensed by the human motion sensor 5 accommodated in the main body portion 2.

[0053] In other methods of fixing devices such as the human motion sensor 5 to clothes, for example, there are clamps using leaf springs or button types using resin elasticity. However, the number of these components tends to increase, and the manufacturing cost also becomes high. In addition, the button-type components are divided into two or more, and there are problems such as the possibility of loss and difficulty in installing on thick clothes.

[0054] Therefore, it is proposed to reduce the manufacturing cost and the number of components by integrating the button-type cover and the housing, and it can also be installed on thick clothes such as Figure 1 and Figure 2 the structure of the fastener 1 with the regulator portion 3 shown.

[0055] <2. Structure of the fastener>

[0056] Next, with reference to Figures 4 to 14 , the structure of the fastener 1 will be described.

[0057] Figures 4 to 8 In Figure 4 ), the top view ( Figure 5 ), bottom view ( Figure 6 ), front view ( Figure 7 ), rear view ( Figure 8 ) of the fastener 1 in the state of unlocking the lock from the main body portion 2 and opening the cover portion 4 (hereinafter, referred to as the unlocked state) are shown respectively. In addition, regarding the left side view, since the structure is substantially the same as that of the right side view, the illustration is omitted.

[0058] And Figures 9 to 14 In Figure 9 ), the top view ( Figure 10 ), bottom view ( Figure 11 ), front view ( Figure 12 ), rear view ( Figure 13 ), right side view ( Figure 9 ), and cross-sectional view taken along A-A of Figure 14 ) of the fastener 1 in the state where the cover portion 4 is locked to the main body portion 2 (hereinafter, referred to as the locked state) are shown respectively. Regarding its left side view, since the structure is also substantially the same as that of the right side view, the illustration is omitted.

[0059] As described above Figures 4 to 14The fastener 1 shown has a main body portion 2, a regulator portion 3, and a cover portion 4. They are formed of a resin such as PE (polyethylene) or PP (polypropylene), for example.

[0060] The main body portion 2 has a housing cover 21 and a receiving housing 22. The main body portion 2 is formed by the upper and lower combination of the housing cover 21 and the receiving housing 22.

[0061] The housing cover 21 is formed in a substantially elliptical cylindrical shape that opens downward. A cylindrical protrusion 24 is formed on the upper surface 23 of the housing cover 21. The cylindrical protrusion 24 is inserted through a circular hole 45 formed in the cover portion 4 described later in the locked state.

[0062] The receiving housing 22 is formed in a substantially elliptical cylindrical shape that opens upward. A plurality of bottom surface holes 26 of a required number are formed on the bottom surface 25 of the receiving housing 22. The sensing surface of the human motion sensor 5 described later is disposed on the bottom surface holes 26.

[0063] As Figure 5 , Figure 10 and Figure 14 shown, a human motion sensor 5 is installed in the internal space formed in the main body portion 2.

[0064] The human motion sensor 5 has one or more detection portions. Sensors such as an optical sensor, a three-axis acceleration sensor, and a temperature sensor are mounted on the human motion sensor 5 as the detection portions, and the back surface is a sensing surface. This sensing surface is exposed to the outside of the main body portion 2 by being disposed on the bottom surface holes 26 of the receiving housing 22.

[0065] As Figure 3 shown, by wearing the fastener 1 on the clothes of the infant Hm, the sensing surface exposed from the bottom surface holes 26 of the main body portion 2 comes into contact with the skin of the infant Hm, so that the pulse, fetal movement, and body temperature can be sensed. The human motion sensor 5 detects abnormalities of the infant based on each sensing information.

[0066] In addition, the human motion sensor 5 can judge the distance from the sensing surface to the skin of the infant Hm based on the light receiving intensity of the optical sensor for measuring the pulse and the like. For example, when the light receiving intensity is weak, the human motion sensor 5 judges that the distance from the human motion sensor 5 to the infant Hm is far (the fastener 1 has fallen off the clothes of the infant Hm).

[0067] The human motion sensor 5 issues an alarm when an abnormality of the infant Hm is detected, and notifies the situation when it is detected that the fastener 1 has fallen off the clothes of the infant Hm.

[0068] In addition, on the bottom surface hole 26, there are also arranged a push button switch for turning on / off the power supply of the human motion sensor 5, or a full-color LED or a charging terminal that constitutes the human motion sensor 5, etc.

[0069] Next, the regulator part 3 will be described following the main body part 2.

[0070] The regulator part 3 is configured to be elastically bendable and is formed into a flat plate shape extending in the front-rear direction from the front end part 27 of the storage case 22 as shown in Figure 5 and Figure 8 . The front end part 31 of the regulator part 3 is connected to the rear end part 44 of the cover part 4.

[0071] As shown in Figure 11 , Figure 13 and Figure 14 , the cover part 4 has a flat surface part 41, a side surface part 42, and a locking part 43.

[0072] The flat surface part 41 is formed into a substantially semi-elliptical shape so as to cover a part of the upper surface 23 of the main body part 2 shown in Figure 9 , for example, less than half. A circular hole 45 is formed in the flat surface part 41. In the locked state, the cylindrical protrusion 24 of the main body part 2 is inserted through the circular hole 45.

[0073] The side surface part 42 protrudes from the circumferential edge part 46 of the flat surface part 41 in the thickness direction and is formed to cover the rear end part of the main body part 2 in the locked state as shown in Figure 13 and Figure 14 .

[0074] The locking part 43 is formed to protrude radially inward from the lower end edge part 47 of the side surface part 42.

[0075] When the cover part 4 is locked to the main body part 2 (set to the locked state), by flexing the regulator part 3, the cover part 4 is placed on the main body part 2 in such a way that the locking part 43 of the cover part 4 contacts the circumferential end part 28 of the bottom surface of the main body part 2. Thus, the rear end part of the main body part 2 is accommodated in the accommodation space formed by the flat surface part 41, the side surface part 42, and the locking part 43.

[0076] At this time, due to the flexural reaction force of the regulator part 3, the locking part 43 of the cover part 4 applies pressure to the main body part 2, and thus the cover part 4 is locked to the main body part 2.

[0077] In this locked state, the side surface 29 of the main body part 2 and the opposing surface 32 of the regulator part 3 opposing the side surface 29 are in a separated state.

[0078] That is, in the state where the cover part 4 covers the main body part 2, it is locked by the main body part 2, but due to the neck-shaped regulator part 3, there is a little degree of freedom in the positioning of the cover part 4 in the locking direction.

[0079] Thus, even if the thickness of the sandwiched clothing fabric 50 is different, an appropriate locking force can be obtained in the sandwiched state.

[0080] And, in the locked state, as Figure 9 , Figure 13 and Figure 14 show, the cylindrical protrusion 24 of the main body portion 2 is in a state of being inserted through the circular hole 45 of the cover portion 4. At this time, the upper surface of the cylindrical protrusion 24 is substantially flush with the upper surface of the cover portion 4. In this state, the cylindrical protrusion 24 is exposed.

[0081] When removing the cover portion 4 from the main body portion 2, the user can easily become a non-locked state by, for example, pressing the thumb or the like against the cylindrical protrusion 24 and lifting the cover portion 4 from the main body portion 2 in a peeling manner.

[0082] In Figure 3 and Figure 15 shows the state of fixing the fastener 1 having the above structure to the clothes.

[0083] Figure 15 is a cross-sectional view taken along the A-A line of the state where the clothing fabric 50 is sandwiched between the main body portion 2 and the cover portion 4. Figure 9 of.

[0084] In the non-locked state, for example, as Figure 3 shows, by putting the main body portion 2 into the clothes of the infant Hm and covering the cover portion 4 in a manner of sandwiching the clothing fabric 50, the fastener 1 is worn on the clothes.

[0085] In such a locked state, as Figure 15 shows, the clothing fabric 50 is sandwiched between the main body portion 2 and the cover portion 4, so that the main body portion 2 is worn on the fabric 50.

[0086] <3. Summary and Variation Examples>

[0087] The fastener 1 in the above embodiment includes: a main body portion 2; a regulator portion 3 that extends from the main body portion 2 and can be elastically bent; and a cover portion 4 that is connected to the main body portion 2 via the regulator portion 3 (refer to Figure 1 and Figure 2 etc.).

[0088] Then, the cover portion 4 is configured to be able to be in a state of separating from the main body portion 2 and a state of being locked to the main body portion 2 in a state of covering the main body portion 2 by the elastic bending of the regulator portion 3 (refer to Figure 4 and Figure 9 etc.).

[0089] Here, in a state where the lid portion 4 is locked to the main body portion 2 (locked state), the side surface 29 of the main body portion 2 and the opposing surface 32 of the regulator portion 3 opposing the side surface 29 are in a separated state (refer to Figure 13 etc.).

[0090] According to the above structure, in the locked state, due to the regulator portion 3 shaped like a neck, there is a little margin in the positioning of the lid portion 4 in the locking direction.

[0091] Therefore, even if the thickness of the cloth 50 of the clothing sandwiched between the main body portion 2 and the lid portion 4 is different, since an appropriate locking force can be obtained in the sandwiched state, it is possible to make it difficult for the fastener 1 to shift during wearing.

[0092] Moreover, even when the article fixed by the fastener 1 (such as the human motion sensor 5 etc.) itself is small, by forming the main body portion 2 and the lid portion 4 integrally, it is possible to easily make the size such that the infant Hm cannot accidentally ingest it.

[0093] In the fastener 1 of the present embodiment, the lid portion 4 is locked to the main body portion 2 in a state of covering a part of the main body portion 2 (refer to Figure 9 and Figure 13 etc.).

[0094] Therefore, in the locked state, less than half of the main body portion 2 is also exposed to the outside. Thus, the heat dissipation efficiency of the human motion sensor 5 mounted on the main body portion 2 can be improved.

[0095] Moreover, by forming the lid portion 4 to cover a part rather than the whole of the main body portion 2, it is possible to reduce the manufacturing cost of the fastener 1.

[0096] In the fastener 1 of the present embodiment, the main body portion 2 has a protruding portion (cylindrical protrusion 24), and the lid portion 4 has an insertion hole (circular hole 45). In a state where the lid portion 4 is locked to the main body portion 2, the cylindrical protrusion 24 is inserted through the circular hole 45 (refer to Figure 9 and Figure 14 etc.). Here, when removing the lid portion 4 from the main body portion 2, for example, while pressing the cylindrical protrusion 24, it is lifted from the main body portion 2 in a manner of peeling off the lid portion 4, and thus it can easily become a non-locked state.

[0097] In the fastener 1 of the present embodiment, a human motion sensor 5 having one or more detection portions capable of detecting the physical condition of the wearer (infant Hm) is mounted on the main body portion 2 (refer to Figure 14 etc.).

[0098] Thus, in a state where the fastener 1 is worn on the fabric 50 of the clothes of the infant Hm by engaging the lid portion 4 with the main body portion 2, the human motion sensor is in contact with the body of the infant Hm. Therefore, the human motion sensor 5 can be easily worn on the clothes of the infant Hm by the fastener 1, and users such as kindergarten teachers, nannies, and parents can easily monitor the physical condition of the infant Hm.

[0099] Moreover, the detection unit at least includes an optical sensor that determines the contact state with the body of the wearer (infant Hm), and the optical sensor is configured to be exposed from a hole (bottom surface hole 26) formed in the main body portion 2 (see Figure 5 and Figure 10 etc.).

[0100] Thus, the wearing state of the fastener 1 can be determined by the optical sensor.

[0101] In addition, in the present embodiment, the article mounted on the main body portion 2 is the human motion sensor 5, but the article is not limited to the human motion sensor 5. Various articles can be mounted on the main body portion 2, and the article can be worn on the fabric 50 via the fastener 1.

[0102] In the present embodiment, the object of wearing the fastener 1 is described as the clothes of the infant Hm. However, in addition to the infant Hm, as long as it is an object such as the clothes of an adult, an elderly person, or an animal, or a curtain in a room that has a thickness like the fabric 50, the fastener 1 can be worn on various objects.

[0103] Finally, the effects described in the present invention are merely illustrative and not limited thereto. Other effects may also be achieved, or only a part of the effects described in the present invention may be achieved. Moreover, the embodiments described in the present invention are merely examples, and the present invention is not limited to the above embodiments. Therefore, naturally, even in a manner other than the above embodiments, as long as it does not depart from the scope of the technical idea of the present invention, various changes can be made according to the design, etc. In addition, the combination of the structures described in the embodiments is not all necessary for solving the problems.
